Abstract

A test device for horizontal position of an optical disc drive, comprising a test platform having a plurality of vertical position rods mounted thereon and the rods being of similar horizontal height; and at least a sensor mounted within the area formed by the position rods located on the platform, and including at least an emitting element and a receiving element, the emitting element emitting an optical detection signal (i.e., incident wave) to an optical disc connectedly driven by the motor rotating shaft of a pick-up mechanism to be tested, by means of a reflected optical signal produced by the optical disc, the receiving element receives the signal, and the sensor produces a horizontal height measuring data, and thereby the results and the measured horizontal height data determine whether the motor horizontal position of the optical disc drive pick-up device is parallel to the horizontal axial direction of the optical disc drive pick-up device.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A test device for horizontal position of an optical disc drive, comprising 
       (a) a test platform having a plurality of vertical position rods mounted thereon and the rods being of similar horizontal height; and  
       (b) at least a sensor mounted within the area formed by the position rods located on the platform, and including at least an emitting element and a receiving element, the emitting element emitting an optical detection signal (i.e., incident wave) to an optical disc connectedly driven by the motor rotating shaft of a pick-up mechanism to be tested, by means of a reflected optical signal produced by the optical disc, the receiving element receives the signal, and the sensor produces a horizontal height measuring data, and thereby the results and the measured horizontal height data determine whether the motor horizontal position of the optical disc drive pick-up device is parallel to the horizontal axial direction of the optical disc drive pick-up device.  
     
     
       2. A test device for horizontal position of an optical disc drive as set forth in  claim 1 , wherein at least an interfacing device is provided to the test platform to transmit the horizontal height data detected by the sensor to the near-end computer and the far-end computer for determination and recording. 
     
     
       3. A test device for horizontal position of an optical disc drive as set forth in  claim 1 , wherein the end terminal of the respective position rods of the test platform is mounted with at least a protruded block for the securing of the four corners of the optical disc drive pick-up device. 
     
     
       4. A test device for horizontal position of an optical disc drive as set forth in  claim 1 , wherein the sensor is a laser optical signal-sensing element. 
     
     
       5. A test device for horizontal position of an optical disc drive as set forth in  claim 1 , wherein the sensor is an infrared optical signal-sensing element.
